Landau, 20th May 2024
Preliminary note
For over 20 years, ACOREMA, in cooperation with the Saint Louis Zoo (Missouri, USA), has been conducting Humboldt Penguin counts at key sites for the National Service of Federally Protected Natural Areas (SERNANP) and the National Reserve System of Guano Islands, Islets and Rocky Headlands (RNSIIPG). The regular surveys are hardly known as they are not published in any specialist journals. Sphenisco was also unaware of the results until now, despite its long and close collaboration with ACOREMA.
